siguors to The Magee Carpet Company, Bloomsburg, Pa., a corporation of Pennsylvania Original application June 26, 1957, Ser. No. 668,100, now Patent No. 2,974,690, dated Mar. 14, 1961. Divided and this application Get. 24, 1960, Ser. No. 70,885 6 Claims. (ill. 139-402) This invention relates to a woven fabric and method of weaving the same.

It is an object of the invention to weave a loop pile fabric on a loom such as disclosed in our prior application filed March 20, 1956, Serial No. 572,657, now Patent No. 2,896,671, wherein pile yarns of dilferent twists in alternate relation are carried over one, two, three or more of the gauge wires in one direction and then carried over the gauge wires in the opposite direction to provide rows of loops in angular relation to the loops in other rows, with the loops formed from yarns of one twist having a different appearance from loops formed from yarns of the other twist whereby a new and novel texture effect is produced.

This application is a division of our prior application Serial No. 668,100, filed June 26, 1957, now Patent No. 2,974,690.

In the accompanying drawings forming a part of this specification and wherein like numerals are employed to designate like parts throughout the same:

FIG. 1 is a weftwise section of fabric woven in accordance with our invention,

FIG. 2 is a perspective view showing the weave of a single pile warp yarn,

FIG. 3 is a cross section of a different weave wherein different twist pile yarns are carried over a plurality of sets of ground warps successively,

FIG. 4 is a view similar to FIG. 3 showing the same pile yarns extending in a reverse weftwise direction over the same sets of ground warps, and,

FIG. 5 is a view of the S and Z twist pile yarns used in Weaving the fabric.

In the drawings, fabrics are shown made in accordance with the method which may be carried out on the gauge type loom disclosed in our prior application Serial No. 572,657, now Patent No. 2,896,671. -In carrying out the method, pile yarns are carried by a series of needles over gauge wires and down into the ground warps to be tied into the ground by the usual weft shots. The needles are then swung upwardly and moved weft-wise to carry the pile yarns over and down on the opposite side of the gauge wires. The mechanism for operating the slide bar supporting the needles is modified to move the needles over one, two or more gauge wires in one direction and then in the reverse direction, or to move the needles successively over a number of gauge wires in one direction and then in a reverse direction.

The pile yarns employed in the method are S and Z multi-ply twist yarns 5 and 6 which when carried over the gauge wires form pile loops 7 of a fabric 8. Each weftwise row of loops includes 8 and Z twist yarns arranged in alternate relation, with the loops in the rows being angularly disposed in relation to the loops in other rows. The fabric shown in FIG. 1 has each row of loops formed of S and Z twist yarns arranged in alternate relation with the yarns forming the loops in one row carried over two gauge wires before being tied between the chain warp threads 9 by the weft threads 10 and then carried in a reverse direction over the same two gauge wires to form the next row of loops. This causes the loops in each row to be angularly disposed with respect to the loops in adjacent rows and due to the different twist of tates Patent the yarns forming the loops and change in the angular direction of the loops it will be seen the loops formed of one twist yarn will have a difierent texture appearance to that of the loops formed of the other twist yarn.

In the fabric shown in FIGS. 3 and 4 there are sets of three 2 twist yarns arranged in alternate relation to sets of three 8 twist yarns, each yarn being carried by a separate needle. The yarns are carried over three gauge wires successively in one direction forming three rows of loops disposed in the same angular direction and then are carried back in the opposite direction over the same three gauge wires successively to form three rows of loops disposed in an angular direction opposite to that of the first three rows of loops. As each of the pile yarns is carried over a gauge wire and down between sets of the ground warps a weft shot is inserted between the ground warps and over the pile yarns. The pile yarns are then carried in the same weftwise direction over another gauge wire and down between sets of ground warps and another weft shot is inserted to tie the pile yarns into the ground. After carrying the pile yarns over two or more gauge wires in the same direction the pile yarns are carried over the same gauge wires in a reverse direction and are tied into the ground warps by weft shots. Due to the change in the angular direction of the loops and the different twists in the yarns it will be seen a pronounced design is formed in the texture of the pile.

The fabrics shown are preferred examples of the same and fabrics of different texture may be formed by varying the arrangement of the S and Z twist yarns or changing the action of carrying the pile yarns over one, two, three or more of the gauge wires in one direction and then reversing the action, or carrying the yarns over two, three or more of the gauge wires successively in one direction and then reversing the action. It is also possible to produce a texture effect by using only an S or Z twist yarn and carrying the yarn over a series of gauge wires in one direction and then over the same wires in a reverse direction, or the yarns can be carried over a series of wires successively in one direction and then over the same wires in a reverse direction.
